Mystery Ranch's Warranty covers defects in manufacturing and materials. When it comes to fire packs, not everything can be repaired, and not all damage is covered under warranty. Burn holes and yoke damage from the dogs and chains of your chainsaw, especially due to negligence (a melted pack from putting it down in hot ash and coals, for instance), are not covered by warranty. We will repair user damage where possible, but a nominal fee will be assessed. We will make sure to clear any potential charges with you prior to repair. Please call with any questions.
